++OMAP2/3 Display Subsystem
++-------------------------
++
++This is an almost total rewrite of the OMAP FB driver in drivers/video/omap
++(let's call it DSS1). The main differences between DSS1 and DSS2 are DSI,
++TV-out and multiple display support, but there are lots of small improvements
++also.
++
++The DSS2 driver (omapdss module) is in arch/arm/plat-omap/dss/, and the FB,
++panel and controller drivers are in drivers/video/omap2/. DSS1 and DSS2 live
++currently side by side, you can choose which one to use.
++
++Features
++--------
++
++Working and tested features include:
++
++- MIPI DPI (parallel) output
++- MIPI DSI output in command mode
++- MIPI DBI (RFBI) output
++- SDI output
++- TV output
++- All pieces can be compiled as a module or inside kernel
++- Use DISPC to update any of the outputs
++- Use CPU to update RFBI or DSI output
++- OMAP DISPC planes
++- RGB16, RGB24 packed, RGB24 unpacked
++- YUV2, UYVY
++- Scaling
++- Adjusting DSS FCK to find a good pixel clock
++- Use DSI DPLL to create DSS FCK
++
++Tested boards include:
++- OMAP3 SDP board
++- Beagle board
++- N810
++
++omapdss driver
++--------------
++
++The DSS driver does not itself have any support for Linux framebuffer, V4L or
++such like the current ones, but it has an internal kernel API that upper level
++drivers can use.
++
++The DSS driver models OMAP's overlays, overlay managers and displays in a
++flexible way to enable non-common multi-display configuration. In addition to
++modelling the hardware overlays, omapdss supports virtual overlays and overlay
++managers. These can be used when updating a display with CPU or system DMA.
++
++Panel and controller drivers
++----------------------------
++
++The drivers implement panel or controller specific functionality and are not
++usually visible to users except through omapfb driver.  They register
++themselves to the DSS driver.
++
++omapfb driver
++-------------
++
++The omapfb driver implements arbitrary number of standard linux framebuffers.
++These framebuffers can be routed flexibly to any overlays, thus allowing very
++dynamic display architecture.
++
++The driver exports some omapfb specific ioctls, which are compatible with the
++ioctls in the old driver.
++
++The rest of the non standard features are exported via sysfs. Whether the final
++implementation will use sysfs, or ioctls, is still open.
++
++V4L2 drivers
++------------
++
++V4L2 is being implemented in TI.
++
++From omapdss point of view the V4L2 drivers should be similar to framebuffer
++driver.
++
++Architecture
++--------------------
++
++Some clarification what the different components do:
++
++    - Framebuffer is a memory area inside OMAP's SRAM/SDRAM that contains the
++      pixel data for the image. Framebuffer has width and height and color
++      depth.
++    - Overlay defines where the pixels are read from and where they go on the
++      screen. The overlay may be smaller than framebuffer, thus displaying only
++      part of the framebuffer. The position of the overlay may be changed if
++      the overlay is smaller than the display.
++    - Overlay manager combines the overlays in to one image and feeds them to
++      display.
++    - Display is the actual physical display device.
++
++A framebuffer can be connected to multiple overlays to show the same pixel data
++on all of the overlays. Note that in this case the overlay input sizes must be
++the same, but, in case of video overlays, the output size can be different. Any
++framebuffer can be connected to any overlay.
++
++An overlay can be connected to one overlay manager. Also DISPC overlays can be
++connected only to DISPC overlay managers, and virtual overlays can be only
++connected to virtual overlays.
++
++An overlay manager can be connected to one display. There are certain
++restrictions which kinds of displays an overlay manager can be connected:
++
++    - DISPC TV overlay manager can be only connected to TV display.
++    - Virtual overlay managers can only be connected to DBI or DSI displays.
++    - DISPC LCD overlay manager can be connected to all displays, except TV
++      display.
++
++Sysfs
++-----
++The sysfs interface is mainly used for testing. I don't think sysfs
++interface is the best for this in the final version, but I don't quite know
++what would be the best interfaces for these things.
++
++The sysfs interface is divided to two parts: DSS and FB.
++

++
++There are also some debugfs files at <debugfs>/omapdss/ which show information
++about clocks and registers.
++
++Examples
++--------
++
++The following definitions have been made for the examples below:
++
++ovl0=/sys/devices/platform/omapdss/overlay0
++ovl1=/sys/devices/platform/omapdss/overlay1
++ovl2=/sys/devices/platform/omapdss/overlay2
++
++mgr0=/sys/devices/platform/omapdss/manager0
++mgr1=/sys/devices/platform/omapdss/manager1
++
++lcd=/sys/devices/platform/omapdss/display0
++dvi=/sys/devices/platform/omapdss/display1
++tv=/sys/devices/platform/omapdss/display2
++
++fb0=/sys/class/graphics/fb0
++fb1=/sys/class/graphics/fb1
++fb2=/sys/class/graphics/fb2
++
++Default setup on OMAP3 SDP
++--------------------------
++
++Here's the default setup on OMAP3 SDP board. All planes go to LCD. DVI
++and TV-out are not in use. The columns from left to right are:
++framebuffers, overlays, overlay managers, displays. Framebuffers are
++handled by omapfb, and the rest by the DSS.
++
++FB0 --- GFX  -\            DVI
++FB1 --- VID1 --+- LCD ---- LCD
++FB2 --- VID2 -/   TV ----- TV
++
++Example: Switch from LCD to DVI
++----------------------
++
++w=`cat $dvi/horizontal | cut -d "," -f 1`
++h=`cat $dvi/vertical | cut -d "," -f 1`
++
++echo "0" > $lcd/enabled
++echo "" > $mgr0/display
++fbset -fb /dev/fb0 -xres $w -yres $h -vxres $w -vyres $h
++# at this point you have to switch the dvi/lcd dip-switch from the omap board
++echo "dvi" > $mgr0/display
++echo "1" > $dvi/enabled
++
++After this the configuration looks like:
++
++FB0 --- GFX  -\         -- DVI
++FB1 --- VID1 --+- LCD -/   LCD
++FB2 --- VID2 -/   TV ----- TV
++
++Example: Clone GFX overlay to LCD and TV
++-------------------------------
++
++w=`cat $tv/horizontal | cut -d "," -f 1`
++h=`cat $tv/vertical | cut -d "," -f 1`
++
++echo "0" > $ovl0/enabled
++echo "0" > $ovl1/enabled
++
++echo "" > $fb1/overlays
++echo "0,1" > $fb0/overlays
++
++echo "$w,$h" > $ovl1/output_size
++echo "tv" > $ovl1/manager
++
++echo "1" > $ovl0/enabled
++echo "1" > $ovl1/enabled
++
++echo "1" > $tv/enabled
++
++After this the configuration looks like (only relevant parts shown):
++
++FB0 +-- GFX  ---- LCD ---- LCD
++     \- VID1 ---- TV  ---- TV
++
++Misc notes
++----------
++
++OMAP FB allocates the framebuffer memory using the OMAP VRAM allocator.
++
++Using DSI DPLL to generate pixel clock it is possible produce the pixel clock
++of 86.5MHz (max possible), and with that you get 1280x1024@57 output from DVI.
++
++Rotation and mirroring currently only supports RGB565 and RGB8888 modes. VRFB
++does not support mirroring.
++
++VRFB rotation requires much more memory than non-rotated framebuffer, so you
++probably need to increase your vram setting before using VRFB rotation. Also,
++many applications may not work with VRFB if they do not pay attention to all
++framebuffer parameters.
++
++Kernel boot arguments
++---------------------
++
++vram=<size>
++	- Amount of total VRAM to preallocate. For example, "10M". omapfb
++	  allocates memory for framebuffers from VRAM.
++
++omapfb.mode=<display>:<mode>[,...]
++	- Default video mode for specified displays. For example,
++	  "dvi:800x400MR-24@60".  See drivers/video/modedb.c.
++	  There are also two special modes: "pal" and "ntsc" that
++	  can be used to tv out.
++
++omapfb.vram=<fbnum>:<size>[@<physaddr>][,...]
++	- VRAM allocated for a framebuffer. Normally omapfb allocates vram
++	  depending on the display size. With this you can manually allocate
++	  more or define the physical address of each framebuffer. For example,
++	  "1:4M" to allocate 4M for fb1.
++
++omapfb.debug=<y|n>
++	- Enable debug printing. You have to have OMAPFB debug support enabled
++	  in kernel config.
++
++omapfb.test=<y|n>
++	- Draw test pattern to framebuffer whenever framebuffer settings change.
++	  You need to have OMAPFB debug support enabled in kernel config.
++
++omapfb.vrfb=<y|n>
++	- Use VRFB rotation for all framebuffers.
++
++omapfb.rotate=<angle>
++	- Default rotation applied to all framebuffers.
++	  0 - 0 degree rotation
++	  1 - 90 degree rotation
++	  2 - 180 degree rotation
++	  3 - 270 degree rotation
++
++omapfb.mirror=<y|n>
++	- Default mirror for all framebuffers. Only works with DMA rotation.
++
++omapdss.def_disp=<display>
++	- Name of default display, to which all overlays will be connected.
++	  Common examples are "lcd" or "tv".
++
++omapdss.debug=<y|n>
++	- Enable debug printing. You have to have DSS debug support enabled in
++	  kernel config.
++
++TODO
++----
++
++DSS locking
++
++Error checking
++- Lots of checks are missing or implemented just as BUG()
++
++System DMA update for DSI
++- Can be used for RGB16 and RGB24P modes. Probably not for RGB24U (how
++  to skip the empty byte?)
++
++OMAP1 support
++- Not sure if needed
